Shen Pengfei returns to his hometown to establish an oil processing factory, offering to buy rapeseed from the villagers of Zhaoshu Village at three yuan per jin. Seeing the high price of cooking oil, the villagers misunderstand his intentions. Wu Jianjun seizes the opportunity to stir up trouble, inciting everyone to demand higher prices and cause a disturbance. They surround the factory and tear up their contracts. Heartbroken, Shen Pengfei turns to Shawan Village, where he promotes standardized cultivation and secures a major order. After Wu Jianjun takes over the rapeseed business, he resorts to fraud and withholds workers' wages. His substandard oil is rejected, forcing him to flee, while the village's entire rapeseed harvest goes to waste. Filled with regret, the villagers come to apologize to Shen Pengfei. He stands firm on his prices and quality standards, helping surrounding villages develop their rapeseed industry and achieve prosperity together.
